Respitory System Andrew Gasaway P2
Volume and preassure relationships in the thoracic cavity
inhaling
Breathe in when volume of air in lungs is lower than Atmospheric pressure
exhaling
Breathe out when volume of air in lungs is higher than Atmospheric pressure

Respitory volumes and capacities
Vital capacity (VC)
TV+ERV+IRV
Total lung capacity (TLC)
VC+RV
Functional residual capacity (FRC)
ERV+RV
Inspiratory capacity (IC)
IRV+TV
Tidal volume (TV)
volume of air that enters or leaves the lungs during one
respiratory cycle;
Expiratory reserve volume (ERV)
volume of air that can be exhaled during a
maximal forced expiration
Inspiratory reserve volume (IRV)
volume of air that can be inhaled in
addition to the tidal volume,
Residual volume (RV)
volume of air that remains in the lungs after a
maximal expiration;
internal vs. external respiration
Internal respiration
Gas exchange between blood and body
External respiration
Gas Exchange between blood and lungs
Lower Respiratory structures and function
Trachea
Fortified with incomplete C shaped structures to keep airway opened.
Bronchial tree
Many branches eventually lead to alveoli where gas exchange occures
Larynx
Keeps particle from entering trachea and houses vocal cords
lungs
2 lungs
Left(2 lobes, superior and inferior)
Right(3 lobes, superior, middle, inferior)
Compare and contrast mechanisms of expiration and inspiration
inspiration
Brings in O2
inhaling
expiration
Brings out CO2
exhaling
Layers of Pleurae
parietel pleura
outer layer
serous fluid
between both membranes(Pleural cavity)
visceral pleura
inner layer
Major functions of the respiratory system
Breath out Carbon Dioxide(CO2)
produces sound
Breath in oxygen
regulates water levels
regulates blood Ph
upper Respiratory structures and functions
Nasal cavity
warm, moisterize, and filter incoming air
sinuses
Reduce head wieght, and serve as resonant voice chambers
Nose
openings for exit and entrance of air
pharynx
Aids in producing sound for speech
